Calcium Carbonate (CaCOâ??) Powder is a naturally occurring mineral composed primarily of calcium and carbon. Known for its high purity, brightness, and low abrasiveness, calcite is widely used across various industrial sectors. It is highly valued for its ability to neutralize acids, enhance mechanical properties, and provide cost-effective filler material. Available in fine white powder with particle size ranging from 40 microns to 10 microns.
Calcium carbonate powder is derived from the mineral calcium carbonate, which is naturally found in rocks and shells. It is a white, odorless powder that is highly versatile and widely used in various industries. In the context of health and wellness, calcium carbonate powder is a popular dietary supplement due to its high calcium content.
Ground calcium carbonate powder is widely recognized for its various advantages. It is known to enhance the strength and durability of materials, making it a popular choice in construction and manufacturing industries. Additionally, it can act as a filler, improving the performance of products like paint, rubber, and plastics. It also offers environmental benefits by reducing the carbon footprint in certain applications.
With a range of uses, ground calcium carbonate powder finds its way into everyday products. From toothpaste to medications, from paper to cosmetics, its versatility is undeniable.
1. Product Overview
Ground Calcium Carbonate (GCC) is a naturally occurring mineral obtained from high-purity
limestone or marble. It is mechanically ground into fine powder without changing its chemical
structure. GCC is widely used in various industrial applications due to its excellent physical and
chemical properties.

Calcium Carbonate
1. Chemical Name: Calcium carbonate
2. Molecular Formula: CaCO3
3. Molecular Weight: 100.09
4. CAS: 471-34-1
5. Shelf life: 24 months
6. Character: It is powder and granular white or colorless, microcrystalline powder. It is stable in air, and it is practically insoluble in water and in alcohol. The presence of any ammonium salt or carbon dioxide increases its solubility in water, but the presence of any alkali hydroxide reduces the solubility.
7. Usage :
1. Food industry
Food additives: used as nutritional fortifiers, acidity regulators, and anti caking agents in foods such as bread, biscuits, and milk powder.
Calcium supplements: used in food to increase calcium content and enhance nutritional value.
2. Pharma industry
Calcium supplements: used for preparing calcium tablets and other calcium supplements to prevent and treat calcium deficiency.
Pharma excipients: used as excipients in pharma formulations for the preparation of tablets and capsules.
